Leading Global Diesel Engine Manufacturer Adopts QualMark Corporation Technology

DENVER--June 8, 2005--QualMark Corporation (OTCBB: QMRK), has been selected by the global leader in diesel engine manufacturing to provide HALT and HASS testing solutions. The multiple chamber agreement calls for immediate delivery of two QualMark Typhoon chambers, with additional units to be delivered over the course of the next few months. The manufacturer will utilize these chambers to support HALT and HASS testing on power inverters for various applications.

"This large order is outstanding," notes Charles Johnston, President and CEO of QualMark, "in that the capital investment decision was based purely on QualMark's immediate ROI (return on investment). This indicates that companies are moving away from traditional testing methodologies and embracing the operational and financial benefits of HALT and HASS." Mr. Johnston concluded, "the paradigm shift in performing HALT and HASS versus traditional long product testing cycles is a primary force in expanding the HALT and HASS total available market."
